试论水力采煤工作面小时落煤量大小的有关因素

A Preliminary Discussion on Factors Affecting the Hourly Face Output in Hydromine

要使水力采煤取得高产高效仅依靠高压水枪提高落煤量是不够的。水枪小时落煤量与工作面小时出煤量应分别讨论，工作面的小时出煤量与很多因素有关。

Abstract. It is far from being enough to simply rely on highpressure monitor to realize high output and efficiency of a hydromine. The amount of coal broken down by the monitor per hour and the face output per hour should be considered separately.The hourly face output is related to a multiple of factors which all call for full attention.
